B.S., University of Pittsburgh
M.S., Ph.D., The Ohio State University

Teaching Interests

At Muhlenberg, Bill has taught mathematics courses of all kinds, from the elementary to the advanced. His favorites involve the history of mathematics — Landmarks of Greek Mathematics (MTH 251), featuring selections from Euclid, Archimedes, and their compatriots, and Landmarks of Modern Mathematics (MTH 252), featuring the equally impressive work of Newton, Euler, Gauss, et. al. These courses provide a glimpse of history’s greatest mathematicians and the theorems that made them famous.

Scholarly Interests

Over the past two decades, Bill has written four books and edited one on the history of mathematics. The first two, Journey Through Genius: The Great Theorems of Mathematics (Wiley, 1990) and The Mathematical Universe (Wiley, 1994), were alternate selections for Book-of-the-Month Club and one or both of them have subsequently been translated into Spanish, German, Italian, Polish, Japanese, Korean, and Chinese. His third book was Euler: The Master of Us All (Mathematical Association of America, 1999), followed by The Calculus Gallery: Masterpieces from Newton to Lebesgue (Princeton University Press, 2005), which surveys landmarks from the calculus, stretching from the late 17th century up to the dawn of the 20th. Finally, his edited volume The Genius of Euler: Selections from His Life and Work (MAA, 2007) was published as part of the celebration of Euler’s 300th birthday.

Bill has been invited to speak on the history of mathematics at a number of U.S. colleges and universities, before the Australian Mathematical Society, at the Smithsonian Institution, on NPR’s “Talk of the Nation: Science Friday,” and at the Swiss Embassy in Washington in recognition of Euler’s Swiss heritage.

We are excited to welcome Bill to the Breckenridge camp in July/August 2018. He will be presenting and assisting for two full days!

Andy Klee


Andy Klee recently retired from a 28-year career working with JD Edwards ERP software. He has consistently created great training opportunities for JDE clients, and he brings that skill along with a passion for mathematics to MathCamp4Adults.

Andy started out majoring in Mathematics while at the University of Michigan, but then detoured to teaching and a career in IT. Being retired has given him the gift of time to get back to his first love. He started taking math classes again in 2017, where he met Kaylee and was impressed with both his teaching and his desire to go deeper than the standard curriculum allowed. Andy enlisted Kaylee and together they created MathCamp4Adults.

The first MathCamp4Adults was held Summer 2017, attracting nine math enthusiasts, who each flew into Albuquerque for the four day camp.

Kaylee Tejeda

Kaylee Tejeda

Primary Instructor
Kaylee Tejeda received both his Bachelor’s and Master’s degrees in Mathematics from the University of New Mexico. He currently teaches undergraduate mathematics courses at Central New Mexico Community College. He spends the little spare time he has honing his programming skills by volunteering as webmaster for several private and non-profit organizations.

Kaylee is excited about being the primary instructor at MathCamp4Adults, as it allows him to explore topics that aren’t normally covered in the traditional college mathematics curriculum. He is especially looking forward to being able to create an exploratory learning environment where participants can discover solutions on their own or working in small groups. He has many years of experience as a tutor in addition to being a traditional instructor, so he is equally comfortable lecturing in front of large groups and working patiently through tough problems with small groups and one-on-one.
